(IE-WIRE CLAMP.

Application filed May 14,

T 0 all whom 2'25 may concern.

Be it known that I, DARGAN P. ELLIOTT, a citizen of the United States of America, residing at Rimini, in the county of Clarendon and State of South Carolina, have invented certain new and useful Improvements in F ence-VVire Clamps, of which the following is a specification.

My presentinvention relates to an improved fence-wire clamp for use in stretching the wire of fences, and is designed as a device for attaching thestretching machine to the wire netting in the construction of fences of this character.

The primary object of the invention is the provision of a device of this character which is simple in construction and Operation, comparatively inexpensive in cost, and which may be attached to and detached from the fence wire with facility and convenience, and when so attached will hold the fence wire without marring or deforming the parts.

To this end the invention consists in certain novel combinations and arrangements of parts involving an eccentric locking bar and connections, as will be hereinafter more fully described and claimed, and in other novel features forming elements of the combinations as will be specified.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention, wherein the parts are combined and arranged according to the best mode I have thus for devised for the practical application of the principles of my invention.

Figure 1 is a top plan view of a device embodying my invention, the parts being shown in clamped position and the fence wire illustrated by dotted lines.

Fig. 2 is a view in elevation showing the device in operative position, partly broken away for convenience of illustration and in dicating the fence wire in diagrammatic form.

Fig. 3 is a transverse sectional view at line 33 of Fig. 2 depicting the grooved upright bar and eccentric looking or clamping bar, in operative relat1on.

Fig. 4: is an edge view of Fig. 2 wlth the upright base bar in longitudinal section.

In the preferred form of the invention as shown in the figures of drawing I have utilized a rectangular upright or base bar 1 of Specification of Letters Patent.

Patented Aug. 23, 1921. 1921. Serial No. 469,617.

hard wood, rectangular in cross section and approximately six feet in length for the accommodation of different widths or heights of wire netting or fence wire indicated as F in Fig. 2. At one side of this bar I provide a curved or rounded groove 2 extending longitudinally thereof, which may terminate near the ends of the bar, but is of sufficient length to accommodate the widest or highest fence wire. At the top and bottom of the upright member I attach a pair of brackets 3 and at, bolts or screws 5 being employed for securing these brackets to the face of the upright. Each of the brackets is fashioned with an angular bearing plate 6 projecting therefrom. for the support of the eccentric clamp bar 8, which preferably is made of hard wood in the form of a cylinder and supported in the bracket plates in open slots 7 therein. In Fig. 1 it will be seen that the slots are disposed angularly to the plane of the bar 1 and are adapted to receive the bearing pins 9 9 at the ends of the eccentric bar 8, washers 10 being provided for engagement with the bearing plates. The bracket plates, pins, and wash ers or heads on the pins, are preferably of metal to insure durability, but in some instances these materials may be changed if desired.

The'eccentric bar is provided with a handle 11 projecting radially therefrom, and in Figs. 1 and 3 the eccentricity of the bar will be noted, the pins 9 being offset from the center of longitudinal axis of the bar in order that the periphery of the cylindrical or round bar 8 may co-act with the curved surface of the groove 2 and clamp the wire netting or fence wire between the periphery of the eccentric bar and the groove of the upright bar 1.

A pair of draft chains, or a single chain, 12 may be attached at the ends to eyes 13 which are bolted in spaced relationship to one edge of the upright bar, and the draft chain is attached to any suitable type of stretching or pulling device for the purpose of stretching the fence wire F to which the eccentric clamp is afiixed.

From the above description taken in connection with my drawings it is apparent that I have provided a simple device, with a minimum number of parts, for performing its required functions, wherein the rotary, eccentric clamping bar may be readily at- 20 shown) attached t the draft chains 12 may tached to theuprightor base bar by slipping the two pins 9 into the open ends of the r 7 slots 7, guided by the washers 10. And

- the handle 11.

When using the device, the eccentric bar is turnedto open positionas in Fig. 4, and the end of the fence wire vmay be slipped through the opening between the eccentric bar and the upri ht bar; or the fence wire may be positione on the upright bar before the eccentric bar is placed in position. In

I I either event, after the. fence wire is in position, the eccentric bar is turned on its pins to clamp the fence wire between the periphery of the eccentric bar and the grooved base bar, and when so clamped, the stretcher (not be operated to stretch the fence wire in usual manner. By a reverse turn of the handle and eccentric bar, the fence Wire may be released for readjustment of the device.

Havin thus fully described my invention, what I c aim and desire to secure by Letters Patent is- 1. In a device as described, the combination with a grooved base bar having end brackets and open, angular bearing slots in said brackets, of a clamp bar co-acting with said grooved bar, a handle bar on said clamp bar, and eccentric bearing pins at the ends of said clamp bar seated in said slots in the end brackets.

2. In a device as described, the combination with a longitudinally grooved bar having end brackets, and integral bearing plates on said brackets having angularly disposed, open bearing slots, of a cylindrical clamp bar having end pins arran ed eccentrically of the longitudinal axis 0 said clamp bar and seated in said open slots, a handle bar on said clamp bar, and means for attaching said grooved bar to a pulling device.

In testimony whereof I have afiixed my signature.
